A note on appearance: Many stem plants, including this one, are harvested in their above-water (emersed) form, and the photo may not reflect how it looks once fully adjusted to life underwater. This one in particular is known to shift leaf color noticeably as it grows — green when submerged, developing red/purple tones as it reaches the surface. Give it a few weeks to acclimate before judging its final look.
